To @ZZ whom 'it may concem: y

Be it, known that I, CHARLES. L. Voler, of lllinneepolis, Hennepin county, Minne Sota, have invented certain new andy .useful limproveinents yin Cerbureters, of whieh'the following is a Specification.

'lhe 'object of my invention is to provide a carhureting machine hy meansy of which air can hel corbureted undl the degree'ot richnessef the mixture easily controlledy p p A further object is to provide e 'carhureter of. large capacity and 'one whieh'will be compact in construction andma'ybe easily end'conveniently setup. y 1 l .The invention consists generallyl in verious conetructions und eoinhinatione, all es described und .A particularly pointed` out in thepleiins.

ln the luceoinpanying drawingeforining pert.{oftliis speeilication, Figurel is a vertical,Sectional View of o. eerbureterembodying `my invention, Fig. 2 is a detailsee. tional view of the lower .portion of t-he inachine,"illustrating,the cerbureting feature ofthe apparatus, Fig. 3 is un :outside View; showingthe arrzingeinent of thepuinp by ineens of which the oil is introducedinto `lil the. drawing, 2 represents the czneing andfnlid l horizontal doors arranged` within `seid Veasing; et differentelevations and forming',-respectively, the bottoms yof chiun-v bers Send 6., The chamber is adapter-l to contain ,u `limited vSi'ipply ot' urlnu'eting lluihenchne gusolene," which isintroduced intotlic chamber throught-he pipe 7 `und :l pump 8. A, The valve S) allows the nir to he forced out oit the chan'iber as the oil llows therein. The chamber (5 formen gzis.iese1 voir and contains u. drum '1.0, pret'ernbl)r cylindrical in forni. This drum is support-v ed hy the floor 3 by menne oit e centrally ur# ranged huh ll. The hub is intcriorlyy th faded to receive a. plug 12. A central orifice '13 is 'torn'led in the plug, communicuting' at its upper end with the chamber 5 und :it its lower end with a tube 14.- which is' carried by the 'plug 12 ond is verticellj movable therewith. "The plug' l2 luis n slot l5 in its upper end to receive un operating tool, and e Sent 1G for zg. needle vulve 17, which is mounted in o cup 18 on the top ot' the chamber 5. A pipe 19 depends from the therewith atits upperl paratns eiland air Iare tained wit-hin thel machine,

:t'rom the upper 'the oil in the pipe 2l "\.pertorated ribs utilized in the eerhureting top of said chamber to the Hoor thereof sind haS-holes'QO. through which theoil may 'How I end seelc its level within orifice in the plug 12 and How down through the tube 14, the lower end of which is open to permit the oil to enter a pipe 21, which is concentric with the hub ll end connected endend at its lower end passes through a floor @Zend the lower the pipe, enter vthe head2?) of the drum lOvand communicates with `thegns chamber 6 beneath thedrum.

apart to form :their chamber 24whieh comisii'itroducedyhy eeuitnhleincens, (not Shown), to the cnrhureting'eppziratus port 26 is provided-.in the well of the huh ll 'leading to; the interior of` the'pipe 2l` yfrom the chamber 6.

fBy means vet the foregoing described :ip-

and I will now dese-mbe the device by ineens oit which the int-reduced end'mein r desired mixture or vinterrningling is obtained f for the pnrpose of curhureting thee'ir. 27jis`- :i hand -inelosingt-he lowerportion et the vdrum 1.() und toi-ming` the leide walls of the nir chamber 2 .v lThis bund has e seriesot shallow 4grooves 28 therein, formed by .o series of oblique or helical ribs on the outer surfzlcoof the bund. .Each of these ribs hes holes 29 therein, forming communicating' *passages between .the chamber (i and the groove through the chalnher 24C. normal levelvof the oil in the cliznnher .fi undl which the nir flowsl from These holesare below the the nir, flowing through the grooves around the drum und. meeting;l the oil as it posses through the holes, vwill be thoroughlyr carhureted byV the time' it is delivered to the upper portion of the chamber G through. the exit ot' the upper end et' the grooves. .lhe 'lenge SO :wound the lower portion ot the drum 10 prevents the air currents; troni rushing out through the holes v2,9 into the body of the oil. After being discharged endsof the grooves, the muy How around in. the chamber G and tinully pese ott' through the pipe 3l to the service pipe et the System. rlhe height ot und the number of' the operation willdepend upon the length of the Jso tube 14, which may be removed with the plug 11 and cut off, or a longer one substi v tuted, whenever it is desired to change thev level of the oil in the chamber 6. The level of 'the oil and the number of ribs employed in the carbureting operation will regulate the degree of richness of the mixture. A draw-off or drain faucet 32 is providedby means of which the contents of the chamber 6 may be discharged.

-In the operation of the machine, the chamber 5 will be filled with gasolene from a suitable supply, and the needle valve 17 being opened, the oil will flow down through the tube 14' to the bottom of the chamber 6,.be tween it and the'head 23. .As the oil is lowered in the chamber 5, avacuum will be formed above it and when the oil in the bot- `tom of the chamber 6 rises to the level of the Vlow grooves between said band and drum and extending around said drum, means for introduclng air into the lower ends of said grooves, said ribs having perforations therein communicating with said grooves and with the space between'sai'd band 'and the wall of said casing, and means for supplying oilto the space between said band and casing. i y

2. A carbureter comprising a casing, a drum therein spaced from the wallsof said casing, a series of hollow ribs extending heli* ally on the outer surface of said drum forming shallow grooves which are open at their lower ends and extend around the l drum and toward the upper portion thereof,

said ribs having perforations therein leading to said grooves, means for supplying air to said grooves, and means for supplying oil to the space between said drum and casing.

3. A carbureter comprising a casing having an oil tank in its upper portion and a gas chamber in its lower portion, means for admitting oil from said oil chamber to said gas chamber and regulating the level therein, a band adapted to be partially submerged in the oil in said gas chamber and having a series of exterorly formed ribs and perfoia tions therein communicating with said gas chamber, said ribs forming a corresponding number of grooves on the opposite side of `said plate, means forming an inner wall forll said grooves, the upper ends of said grooves being open to said chamber, and means for directing air into the lower portions of said grooves and causing it to iiow upwardly therein past said perforations, said perforations being normally below the level of the oil in saidgas chamber.

4. A carbureter comprising a casing, a drum therein spaced from the wall of said casing and having an air chamber in its lower portion, the space between said drum and casing being adapted to contain a series lof ribsinclosing the lower portion of said drum, some of said ribs bein submerged within the oil in said casing, said'ribs form- .ing a corresponding number of grooves extending around said drum and helically thereon, said grooves being open at their upper and lower ends and said ribs having perforations through which the oil may iow in to said grooves, said air chamber in the lower portion of said drum communicating with the lower ends of said grooves and through which the air is directed past said perforations, the degree of richness of the air being regulated by the level of the liquid in said casing and the number of perfom-4 tions exposed thereto, and means for regulatingthe level of the oil-in said casing.

In witness whereof, I have hereunto set my hand this 16th day of September 1910.
